一般說明
蛋白质组学级糖苷酶F经过从稀磷酸钾缓冲液中充分纯化和冻干，以生产出稳定的产品。 本品不含甘油和其他稳定剂，并且缓冲盐含量非常低。 这种高度纯化的材料非常适用于凝胶、溶液或印迹膜中糖蛋白或糖肽的N-连接去糖基化。
應用
来源于脑膜脓毒性黄杆菌（Elizabethkingia meningoseptica） 的PNGase F已被用于:
- 寨卡20病毒E蛋白的去N-糖基化
- 采用表达 CAR 的 COS 细胞评估柯萨奇病毒和腺病毒受体的糖基化
- 验证 MHC 1 类多肽相关序列 A（MICA）的 N连接糖基化
适用于蛋白质组学和糖生物学；与MALDI-TOF MS分析相容
用于使蛋白质去糖基化。
生化／生理作用
从糖蛋白切割整个聚糖，前提是糖基化天冬酰胺部分在其氨基和羧基末端被多肽链取代。
單位定義
一个酶活性单位是指在37℃、pH 7.5条件下通过SDS-PAGE监测，在1分钟内催化1nM变性核糖核酸酶B释放N-连接寡糖所需的酶量。 糖苷酶F活性的一个Sigma单位相当于1 IUB毫单位。
